This document discusses trends in television and video technology. It notes that uncompressed high definition video requires a high data transfer rate of 90MB/s for 25 frames per second. Current internet speeds like 3G, broadband, WiFi and USB 2.0 cannot support such high data rates. The document then covers topics like interlacing, deinterlacing, video compression standards, and considerations for editing uncompressed video. It goes on to discuss internet broadcasting techniques like adaptive bitrate streaming that allow high quality video over varying internet speeds. The future of television is predicted to include ever higher resolutions like 4K and 8K ultra high definition video.

8. DAX IS A
LOT OF
DATA
1 FRAME = 1280X720 PIXEL
= 921, 600 PIXELS
EACH PIXEL HAS 32BIT COLOUR
SO
1 FRAME = 3.5MB
3.5MB X 25 = 90MB/S

1 FRAME = 3.5MB 3.5MB X 25 = 90MB/S
3G = 0.5MB/S BROADBAND = 5MB/S
WIFI = 50MB/S USB 2.0 = 57MB/S

MPEG4
NEW COMPRESSION SYSTEMS EMERGE ABOUT EVERY 10 YEARS.
LARGELY BECAUSE OF CHIP SPEED.
MPEG 2 1993, MPEG 4 AVC 2003, MPEG HVC DUE IN 2013.
EACH SYSTEM USUALLY TWICE AS EFFICIENT AS LAST.
WHAT ARE THE LIMITS? NO ONE KNOWS.
